DETAILED DESCRIPTION
[0041] Technical solutions in embodiments of the present disclosure
will be described clearly and completely with reference to the
accompanying drawings in the embodiments of the present disclosure.
Obviously, the described embodiments are merely some but not all of
embodiments of the present disclosure. All other embodiments made
on the basis of the embodiments of the present disclosure by a
person of ordinary skill in the art without paying any creative
effort shall be included in the protection scope of the present
disclosure.
[0042] Some embodiments of the present disclosure provide a display
method of a display device. The display device, as shown in FIG.
1a, includes a display panel 10 and a micro lens array 20 disposed
on a display side of the display panel 10. The micro lens array 20
includes a plurality of micro lenses 201 arranged in an array. The
display panel 10 includes a plurality of pixels 101 arranged in an
array.
[0043] Each micro lens 201 is configured to converge light emitted
by pixels 101 that correspond to the micro lens 201. The micro lens
201 is for example a lens formed of a transparent resin material or
other optical device such as a liquid crystal lens, which is not
limited in the present disclosure.
[0044] As shown in FIG. 1a, a display area of the display panel 10
is, for example, divided into a plurality of sub-image units 30
arranged in an array. Each sub-image unit 30 includes multiple
pixels of the plurality of pixels 101. That is, the plurality of
pixels 101 of the display panel 10 is divided into a plurality of
groups, and each group includes multiple pixels of the plurality of
pixels 101. When a 3D image is to be displayed, the 3D image is
divided into a plurality of sub-images, and each sub-image is
loaded into a corresponding sub-image unit 30 in the display panel
10. In this case, the plurality of sub-image units 30 are
integrated to load and display three-dimensional information in the
3D image. In some embodiments, each sub-image unit 30 corresponds
to one micro lens 201. A length L of the sub-image unit 30 is the
same as or approximately the same as a longitudinal length of the
micro lens 201 that corresponds to the sub-image unit 30.
[0045] In some embodiments, a distance g between the display panel
10 and an optical center of a micro lens 201 in the micro lens
array 20 is the same as or approximately the same as a focal length
of the micro lens 201. In this case, light emitted from each pixel
101 is imaged on a central depth plane O-O' after passing through
the micro lens 201 that corresponds to the pixel 101, and the
images of all the pixels 101 on the central depth plane O-O' are
integrated to form a 3D image. Based on this, the display device is
for example a device that realizes glasses-free 3D display using
the integrated imaging principle.
[0046] In addition, as shown in FIG. 1b, the display device further
includes a driving system 40, a controller 41, and a signal
processor 42.
[0047] The controller 41 is configured to set at least one preset
path within one frame. Each preset path has at least two stopping
positions thereon.
[0048] The driving system 40 is connected to the controller 41, and
the display panel 10 and/or the micro lens array 20. The driving
system 40 is configured to drive, according to the at least one
preset path, the display panel 10 and/or the micro lens array 20 to
move along respective preset path(s), and is configured to control
the display panel 10 and/or the micro lens array 20 that move along
the respective preset path(s) to stop moving and maintain a
stopping state within a preset time duration at corresponding
stopping positions.
[0049] It can be understood that in a case where the driving system
40 is connected to the display panel 10 rather than the micro lens
array 20, the driving system 40 drives the display panel 10 to move
along a preset path. In a case where the driving system 40 is not
connected to the display panel 10 but is connected to the micro
lens array 20, the driving system 40 drives the micro lens array 20
to move along a preset path. In a case where the driving system 40
is connected to both the display panel 10 and the micro lens array
20, the driving system 40 drives the display panel 10 to move along
a preset path, or drives the micro lens array 20 to move along a
preset path, or, drives the display panel 10 and the micro lens
array 20 to move along respective preset paths. In FIG. 1b, the
driving system 40 is connected to both the display panel 10 and the
micro lens array 20.
[0050] The signal processor 42 is connected to the controller 41
and the display panel 10. The signal processor 42 is configured to,
in response to stopping of the display panel 10 and/or the micro
lens array 20 at the corresponding stopping positions, provide
display sub-images to the display panel 10 according to one frame
of display image and the at least one preset path. Within one
frame, the display sub-images that correspond to stopping positions
in one of the at least one preset path are overlaid as the frame of
display image.
[0051] Based on this, as shown in FIG. 2, the display method
includes steps 101-104 (S101-S104).
[0052] In S101, the controller 41 sets at least one preset path.
Each preset path has at least two stopping positions thereon.
[0053] In S102, within one frame, the driving system 40 drives the
display panel 10 and/or the micro lens array 20 to move along
respective preset path(s) according to the at least one preset path
so that all the pixels 101 of the display panel 10 are relatively
displaced with respect to the micro lenses 201 that correspond to
respective pixels 101, and controls the display panel 10 and/or the
micro lens array 20 to stop displacing and maintain a stopping
state within a preset time duration at corresponding stopping
positions.
[0054] It will be noted that the display panel 10 does not display
an image during the relative displacement with respect to the micro
lens array 20, and the display panel 10 displays the display
sub-image when the display panel 10 or the micro lens array 20 is
at the above described stopping positions.
[0055] In S103, at the at least two stopping positions, the signal
processor 42 provides display sub-images to the display panel 10
according to the at least one preset path and one frame of display
image, and pixels 101 in the display panel 10 emit light according
to display sub-image signals.
[0056] It will be noted that the setting of the above described
preset time duration needs to meet the requirement that the
displacement and the stopping actions of the pixels cannot be
recognized by human eyes within one frame.
[0057] In S104, each micro lens 201 converges light emitted by
pixels 101 that correspond to the micro lens 201, so that images
are formed on a side of the micro lens 201 away from the display
panel 10.
[0058] As shown in FIG. 1a, the light emitted by pixels 101 of each
sub-image unit 30 in the display panel 10 will be converged to an
intersection point after refracted by the micro lens 201 that
correspond to the pixels 101. The plane in which a plurality of
intersection points are located is the central depth plane
O-O'.
[0059] As shown in FIG. 3a, in some embodiments, a spacing P
between two adjacent pixels of the plurality of pixels 101 for
defining the intrinsic resolution of the display panel 10 is
sufficiently large. For example, the spacing P is the same as or
approximately the same as a width h of one pixel 101, or larger
than the width h of the pixel 101. Based on this, when the above
described S102 is performed, after display panel 10 is moved to the
right, for example, along an arrow shown in FIG. 3a, the movement
is stopped at one stopping position (for example, the stopping
position 2 shown in FIG. 3b), and the stopping state is maintained
at the stopping position within a preset time duration. In this
case, as shown in FIG. 3b, a superposed pixel 102 is formed between
two adjacent pixels 101.
[0060] At this time, as shown in FIG. 3c, light emitted from the
superposed pixel 102 formed between two adjacent pixels 101 at the
stopping position passes through the micro lens 201 that correspond
to the superposed pixel 102 and is imaged on the central depth
plane O-O' to form an image S3. The image S3 is located between the
image S1 and the image S2 that are formed by the two intrinsic
pixels 101 that is adjacent to the superposed pixel 102.
[0061] In some embodiments, the spacing P between two adjacent
pixels of the plurality of pixels 101 for defining the intrinsic
resolution of the display panel 10 is relative small. For example,
the spacing P is less than half of the width of one pixel 101.
Based on this, after the above described S102 is performed, as
shown in FIGS. 4a and 4b, orthographic projections of the same
pixel 101 on a plane where the pixel is located when it is located
at any two different stopping positions in the same preset path
have an overlapping region.
[0062] As shown in FIG. 4a, the arrow indicates the direction of
displacement of the intrinsic pixel 101 in the display panel 10
along a preset path. In this case, the original position of the
pixel 101 can be set to the stopping position 1, and then the
display panel 10 is moved so that a relative displacement exists
between the display panel 10 and the micro lens array 20. The pixel
101 is displaced to the right along the direction of the arrow, and
is stopped from displacing at the stopping position 2. The stopping
state is maintained within a preset time duration at the stopping
position 2. In this case, as shown in FIG. 4a, for any pixel 101,
an orthographic projection of the pixel 101, when the pixel is
located at the stopping position 2, on a plane where the pixel is
located has an overlapping region with an orthographic projection
of the pixel 101 on the plane when it is located at the stopping
position 1, thereby the pixel 101 is divided into a pixel 102_A and
a superposed pixel 102_B. Furthermore, the orthographic projection
of the pixel 101 on the plane when the pixel is located at the
stopping position 2 also has an overlapping region with an
orthographic projection of another pixel 101' located on the right
side of the pixel 101 on the plane when the pixel 101' is located
at the stopping position 1, thereby forming a superposed pixel
102'_A in the overlapping region. It will be noted that since the
orthographic projection of the pixel 101 on the plane when the
pixel 101 is located at the stopping position 1 has an overlapping
region with an orthographic projection of yet another pixel 101
located on the left side of the pixel 101 on the plane when the yet
another pixel 101 is located at the stopping position 2, and this
overlapping region is just the region where the pixel 102_A is
located, the pixel 102_A is actually also a superposed pixel
102_A.
[0063] In this case, as shown in FIG. 4c, light emitted from the
superposed pixels that are formed at each of the stopping
positions, such as the above described superposed pixel 102_A, the
superposed pixel 102_B and the superposed pixel 102'_A,
respectively form an image S1 (the image of the superposed pixel
102_A), an image S2 (the image of the superposed pixel 102_6), and
an image S3 (the image of the superposed pixel 102'_A) on the
central depth plane O-O' after passing through the micro lens 201
that corresponds to the superposed pixels.
[0064] It can be seen from the above description that in the
display method provided in the embodiments of the present
disclosure, at least one preset path may be set by the controller
41 within one frame, and each preset path has at least two stopping
positions. Then, the driving system 40 drives the display panel 10
and/or the micro lens array 20 to move along respective preset
path(s) according to the at least one preset path, so that relative
displacements exist between all the pixels 101 of the display panel
10 and the micro lenses 201 that correspond to the respective
pixels 101, and at each stopping position on the preset path, all
the pixels 101 and/or the micro lenses 201 maintain a stopping
state within a preset time duration. In this case, after all the
pixels 101 are relatively displaced with respect to the micro
lenses 201 that correspond to the pixels 101, the superposed pixel
102 can be formed between any two adjacent pixels of the pixels 101
for defining the intrinsic resolution of the display panel 10.
Alternatively, it is possible that orthographic projections of the
same pixel 101, when it is located at different stopping positions
in the same preset path, on the plane have an overlapping region,
so that a plurality of superposed pixels 102 can be obtained from
one intrinsic pixel 101. On this basis, the signal processor 42
provides display sub-images to the display panel 10 at the stopping
positions according to the at least one preset path and one frame
of display image, so that images of the superposed pixels 102
formed at each of stopping positions are formed on the central
depth plane O-O' after light emitted from the superposed pixels 102
passing through the micro lenses 201 that correspond to the
superposed pixels 102. In this way, within one frame, an image to
be displayed by one intrinsic pixel 101 can be formed by
superposing the images displayed by a plurality of superposed
pixels 102 that are obtained from the intrinsic pixel 101 within
the time range in which the overlapping cannot be recognized by
human eyes, so that one intrinsic pixel 101 displays more contents,
thereby improving the resolution.
[0065] The manner in which the display panel 10 and/or the micro
lens array 20 are relatively displaced along the at least one
preset path is exemplified in detail below.
[0066] In this manner, a parallel relative displacement occurs
between the display panel 10 and the micro lens array 20. In this
case, a plane where each of the at least one preset path set by the
controller 41 is located is parallel to a light exit surface of the
display panel 10 or a light exit side surface of the micro lens
array 20.
[0067] FIG. 5 shows a case where the micro lens array 20 is fixed
and the display panel 10 is moved along a preset path. In FIG. 5,
the preset path (shown by the arrow line) is provided with four
stopping positions (1, 2, 3, and 4) thereon. The first stopping
position 1 is the initial position of the display panel 10. As
shown in FIG. 3a, the display panel 10 has a plurality of pixels
101 arranged in a matrix at the stopping position 1. The plurality
of pixels 101 determine the intrinsic resolution of the display
panel 10. A spacing P between any two adjacent intrinsic pixels 101
is greater than a width h of one pixel 101, or the same as or
approximately the same as the width h of the pixel 101. It will be
noted that the case where the spacing P between any two adjacent
intrinsic pixels 101 is approximately the same as the width h of
one pixel 101, includes the case where the spacing P is slightly
smaller than the width h of the pixel 101. The area of the
overlapping region of the superposed pixel 102 that is formed
between the two adjacent pixels 101 and the pixels 101 on both
sides of the superposed pixel 101 are small; therefore, the display
contents in the overlapping region are negligible.
[0068] In this case, light emitted from each pixel 101 can be
imaged on the central depth plane O-O' after passing through the
micro lens 201 that corresponds to the pixel 101. For example, as
shown in FIG. 6a, an image S1 (the image of the left pixel 101) and
an image S2 (the image of the right pixel 101) are formed on the
above described central depth plane O-O' after light emitted from
the two adjacent intrinsic pixels 101 passes through their
corresponding micro lens 201.
[0069] On this basis, the above described S102 in which the driving
system 40 drives the display panel 10 and/or the micro lens array
20 to move along respective preset path(s) according to the at
least one preset path so that relative displacements exist between
all the pixels 101 of the display panel 10 and the micro lenses 201
that correspond to the respective pixels 101, and controls the
display panel 10 and/or the micro lens array 20 to stop displacing
at corresponding stopping positions, as shown in FIG. 10, includes
steps 1021 and 1022 (S1021 and S1022).
[0070] In S1021, the driving system 40 drives the display panel 10
to move along a corresponding preset path of the at least one
preset path according to the corresponding preset path so that
relative displacements exist between all the pixels 101 of the
display panel 10 and the micro lenses 201 that correspond to the
respective pixels 101, all the pixels 101 of the display panel 10
are horizontally moved to the second stopping position along the
corresponding preset path, and in the horizontal direction, a
superposed pixel 102 that is located at the second stopping
position is formed between any two adjacent pixels 101.
[0071] That is, the driving system 40 drives the display panel 10
to move according to the corresponding preset path, so that
horizontal relative displacements exist between all the pixels 101
of the display panel 10 and the micro lenses 201 that correspond to
the respective pixels 101. The intrinsic pixels 101 in the display
panel 10 are horizontally moved to the right within the plane XOY,
for example, along the direction of the arrow in FIG. 3a. The plane
XOY is parallel to the light exit surface of the display panel 10
or the light exit side surface of the micro lens array 20. In this
case, as shown in FIG. 3b, all the pixels 101 of the display panel
10 are horizontally moved to the second stopping position 2 along
the corresponding preset path, and in the horizontal direction
within the plane XOY, a superposed pixel 102 is formed between two
adjacent pixels 101 of the pixels for determining the intrinsic
resolution of the display panel 10 at the second stopping position
2.
[0072] It will be noted that since when a horizontal relative
displacement occurs between the display panel 10 and the micro lens
array 20, the plane where the preset path is located (the plane
XOY) is parallel to the light exit surface of the display panel 10
or the light exit side surface of the micro lens array 20, after
the display panel 10 is horizontally moved along a preset path
within a plane (the plane XOY) where the preset path is located,
i.e., moved along the X-axis direction, the formed superposed pixel
102 can be in the same row as the intrinsic pixel 101.
[0073] Similarly, after the display panel 10 are vertically moved
along a preset path within a plane (the plane XOY) where the preset
path is located, i.e., moved along the Y-axis direction, the formed
superposed pixel 102 can be in the same column as the intrinsic
pixel 101.
[0074] As shown in FIG. 6b, two of superposed pixels are taken as
an example, and an image S1' (the image of the left superposed
pixel 102) and an image S2' (the image of the right superposed
pixel 102) are formed on the central depth plane O-O' after light
emitted from the two formed superposed pixels 102 passes through
the micro lens 201 that corresponds to the superposed pixels 102.
In this way, increasing the superposed pixel 102 on the right side
of the intrinsic pixel 101 may double the number of images of the
display panel 10 on the central depth plane O-O' within one frame,
thereby doubling the resolution of one frame of image.
[0075] In S1022, the driving system 40 drives the display panel 10
according to the corresponding preset path so that relative
displacements exist between all pixels 101 of the display panel 10
and the micro lenses 201 that correspond to the respective pixels
101, all pixels 101 of the display panel 10 are vertically moved to
the third stopping position along the corresponding preset path,
and in the vertical direction, a superposed pixel 102 that is
located at the third stopping position and is adjacent to the
superposed pixel 102 of the second stopping position is formed.
[0076] That is, on the basis that all pixels 101 of the display
panel 10 are horizontally moved to the second stopping position 2
along the corresponding preset path, the driving system 40
continues to drive the display panel 10 so that vertical relative
displacements of all pixels 101 of the display panel 10 with
respect to the micro lenses 201 that correspond to the respective
pixels 101 occur. For example, within the plane XOY, the intrinsic
pixels 101 in the display panel 10 are vertically moved upward
along the direction of the arrow in FIG. 3b. In this case, as shown
in FIG. 3d, all pixels 101 of the display panel 10 are vertically
moved to a third stopping position 3 along the corresponding preset
path, and in the vertical direction within the plane XOY, the
superposed pixels 102 that are located at the third stopping
position 3 and are adjacent to the superposed pixels 102 located at
the second stopping position 2 are formed (that is, the superposed
pixels 102 located at the upper right corner of the intrinsic
pixels 101). Based on this, three images can be respectively formed
on the central depth plane O-O' after light emitted from an
intrinsic pixel 101, a superposed pixel 102 located at the right of
the pixel 101 and a superposed pixel 102 located at the upper right
corner of the pixel 101 passes through the micro lens 201 that
corresponds to the intrinsic pixel 101 and each of superposed
pixels 102. Thus, the number of images of the display panel 10 on
the central depth plane O-O' within one frame is further increased
to achieve the purpose of further improving the resolution.
[0077] In S1023, the driving system 40 drives the display panel 10
to move according to the corresponding preset path so that relative
displacements between all pixels 101 of the display panel 10 and
the micro lenses 201 that correspond to the respective pixels 101
occur, all pixels of the display panel 10 are horizontally moved to
the third stopping position along the corresponding preset path,
and in the vertical direction, the superposed pixels 102 that are
located at the fourth stopping position and are adjacent to the
superposed pixels 101 located at the first stopping position are
formed.
[0078] That is, on the basis that all pixels 101 of the display
panel 10 are vertically moved to the third stopping position 3
along the corresponding preset path, the driving system 40
continues to drive the display panel 10 so that horizontal relative
displacements of all pixels 101 of the display panel 10 with
respect to the micro lenses 201 that correspond to the respective
pixels 101 occur. For example, within the plane XOY, the intrinsic
pixels 101 in the display panel 10 are moved to the left along the
direction of the arrow in FIG. 3d. In this case, as shown in FIG.
3e, all pixels 101 of the display panel 10 are horizontally moved
to a fourth stopping position 4 along the corresponding preset
path, and in the vertical direction within the plane XOY, the
superposed pixels 102 that are located at the fourth stopping
position 4 and are adjacent to the superposed pixels 101 located at
the first stopping position 1 are formed (that is, the superposed
pixels 102 located at the upward side of the intrinsic pixels 101).
Based on this, fourth images can be respectively formed on the
central depth plane O-O' after light emitted from an intrinsic
pixel 101, a superposed pixel 102 located at the right of the pixel
101, a superposed pixels 102 located at the upper right corner of
the pixel 101 and a superposed pixels 102 located at the upward
side of the intrinsic pixel 101 passes through the micro lenses 201
that correspond to the intrinsic pixels 101 and each of superposed
pixels 102. Thus, the number of images of the display panel 10 on
the central depth plane O-O' within one frame is further increased
to achieve the purpose of further improving the resolution.
[0079] In some embodiments, in the case where the above described
four stopping positions are set on a corresponding preset path of
the at least one preset path, the above described S103, in which at
the at least two stopping positions, the signal processor 42
provides display sub-images to the display panel 10 according to
the at least one preset path and one frame of display image,
includes: the signal processor 42 sequentially dividing one frame
of display image into four display sub-images according to the
order of the stopping positions on the corresponding preset path,
and each display sub-image corresponding to one stopping
position.
[0080] Based on this, after the display panel 10 and the micro lens
array 20 are relatively displaced along the at least one preset
path, the users' eyes are able to superpose the display sub-image
displayed by intrinsic pixels 101 with the display sub-images
respectively displayed by the superposed pixels 102 that are formed
around the intrinsic pixels 101, thereby observing the above
described one frame of display image.
[0081] On this basis, in order to facilitate displaying of the next
frame of image, superposed pixels 102 are formed around each of the
intrinsic pixels 101. In some embodiments, within the plane XOY,
the downward movement of the intrinsic pixels 101 in the display
panel 10 along the direction of the arrow in FIG. 3e is achieved
through parallel relative displacement between the display panel 10
and the micro lens array 20. At this time, the intrinsic pixels 101
in the display panel 10 are returned to the above described first
stopping position 1 (as shown in FIG. 3a). In this case, the
starting point and the end point of the corresponding preset path
overlap. In this way, when a next frame of image is displayed, the
display panel 10 and/or the micro lens array 20 can start to move
from a same starting position as a previous frame of image.
Thereby, the setting manner of the at least one preset path may be
simplified, so that the display image of the pixels 101 for
determining the intrinsic resolution of the display panel 10 may be
more easily allocated to the newly added superposed pixels 102 of
the next frame.
[0082] As can be seen from the above description, in the process of
relative displacement between the display panel 10 and the micro
lens array 20, when the display panel 10 or the micro lens array 20
is located at a stopping position twice, for example, when the
starting point and the end point of the preset path overlap, the
relative positions of the display panel 10 and the micro lens array
20 do not change at the same stopping position, so no new
superposed pixel 102 can be formed around the intrinsic pixels 101.
Therefore, in order to improve the resolution of the display panel
10, any two stopping positions on the same preset path except the
starting point and the end point are different.
[0083] Furthermore, in order to enable the images respectively
displayed by the respective superposed pixels 102 to be uniformly
overlaid, in some embodiments, the distances between two adjacent
stopping positions are the same.
[0084] The above description is made by taking an example in which
the spacing P between two adjacent intrinsic pixels 101 of the
display panel 10 is sufficiently large, such that a newly added
superposed pixel 102 is formed between two adjacent pixels 101
after the display panel 10 is moved. In this case, for the display
panel 10 having a low intrinsic resolution, it is still possible to
display an image with a higher resolution without increasing the
number of intrinsic pixels 101 in the manufacturing process,
thereby simplifying the manufacturing process and reducing the
production cost.
[0085] In a case where the spacing between two adjacent intrinsic
pixels 101 of the display panel 10 is small, in some embodiments,
the spacing between two adjacent pixels 101 of the display panel 10
is less than a half of a width h of one pixel 101. The above
described S102, in which the driving system 40 derives the display
panel 10 and/or the micro lens array 20 to move along respective
preset path(s) according to the at least one preset path so that
all the pixels 101 of the display panel 10 are relatively displaced
with respect to the micro lenses 201 that correspond to respective
pixels 101, and controls the display panel 10 and/or the micro lens
array 20 to stop displacing at corresponding stopping positions, as
shown in FIG. 11, includes steps 1024 and 1025 (S1024 and
S1025).
[0086] In S1024, the driving system 40 drives the display panel 10
to move according to a corresponding one of the at least one preset
path so that relative displacements exist between all pixels 101 of
the display panel 10 and the micro lenses 201 that correspond to
the respective pixels 101, and all pixels 101 of the display panel
10 are horizontally moved to a second stopping position 2 along the
corresponding preset path.
[0087] The first stopping position 1 is for example the initial
position of the display panel 10.
[0088] As shown in FIG. 4a, intrinsic pixels 101 of the display
panel 10 are taken as an example, and the pixels 101 horizontally
move to the second stopping position 2 along the preset path from
the first stopping position 1 (the dashed box in FIG. 4a).
[0089] In S1025, as shown in FIG. 4a, for each pixel 101, an
orthographic projection of the pixel 101, when the pixel 101 is
located at the second stopping position 2, on a plane where the
pixel 101 is located has an overlapping region with orthographic
projections of the pixel 101 and another pixel 101' that is
adjacent to the pixel 101 on the plane when they are located at the
first stopping position 1, and a superposed pixel 102_B and a
superposed pixel 102_A' are formed in respective overlapping
regions.
[0090] For each pixel 101, a superposed pixel 102_B is formed in
the overlapping region between the orthographic projections of the
pixel 101 when it is located at the second stopping position 2 and
the pixel 101 (shown by solid line) when it is located at the
initial position (the first stopping position 1) on the plane. For
another pixel 101' (shown by the dashed box) adjacent to the pixel
101, a superposed pixel 102'_A is formed in the overlapping region
between the orthographic projections of the pixel 101' when it is
located in the first stopping position 1 and the pixel 101 when it
is located at the second stopping position 2 on the plane.
[0091] In this case, the above described S103, in which at the
least two stopping positions, the signal processor 42 provides
display sub-images to the display panel 10 according to the at
least one preset path and one frame of display image, as shown in
FIG. 12, includes steps 1031 and 1032 (S1031 and S1032).
[0092] In S1031, the signal processor 42 sequentially divides one
frame of display image into at least two display sub-images
according to the at least two stopping positions (for example, the
first stopping position 1 and the second stopping position 2), and
each display sub-image corresponds to one stopping position.
[0093] In S1032, the display sub-image received by the superposed
pixels 102 is overlaid with the display sub-image received by the
pixels 101 that are located in the same overlapping region as the
superposed pixel 102.
[0094] The superposed process of the above described display
sub-images will be described below by taking the gray scale value
as an example. For example, since the superposed pixel 102_B is
formed by superposing orthographic projections of the pixel 101
when it is located at the second stopping position 2 and the
initial position (the first stopping position 1) on the plane, the
value of the gray scale displayed by the superposed pixel 102_B is
the value obtained by superposing the value of the gray scale
displayed by the intrinsic pixel 101 with the value of the gray
scale displayed by the pixel 101 when it is moved to the second
stopping position 2. It is assumed that the target value of the
gray scale needed to be displayed by the superposed pixel 102_B is
80, and the value of the gray scale displayed by the intrinsic
pixel 101 before moving (the first stopping position 1) is 60. In
this case, the value of the gray scale displayed by the superposed
pixel 102A is also 60. Then only when the pixel 101 moves to the
second stopping position 2, and the value of the gray scale
displayed by the pixel 101 that is located at the second stopping
position 2 is 20, the superposed pixel 102_B located at the above
described overlapping region displays a gray scale with a value of
80.
[0095] Furthermore, the superposed pixel 102'_A is formed by
overlapping the orthographic projection of the pixel 101' on the
plane when it is located at the first stopping position 1 with the
orthographic projection of the pixel 101 on the plane when it is
located at the second stopping position 2, such that the target
value of the gray scale needed to be displayed by the superposed
pixel 102'_A is a gray scale value after superposing the value of
the gray scale displayed by the pixel 101' with the gray scale
value of the pixels 101 when it is located at the second stopping
position 2 by adjusting the value of the gray scale displayed by
the pixel 101' before movement (the first stopping position 1). The
adjustment process of the target value of the gray scale displayed
by the rest superposed pixels is the same as described above, and
it is unnecessary to go into details here.
[0096] Furthermore, as shown in FIG. 4b, when the third stopping
position 3 and the fourth stopping position 4 are also disposed on
the preset path, one pixel 101 can be divided into four superposed
pixels 102. At this time, the formation process of the above
described superposed pixels and the superposed display process of
the display sub-images are the same as described above, and it is
unnecessary to go into details here.
[0097] The embodiments in which the display panel 10 and/or the
micro lens array 20 are relatively displaced along the at least one
preset path are exemplified in detail below. On the premise that
the display panel 10 and the micro lens array 20 are relatively
displaced, the manners of movement are not limited, including but
not limited to the following manners.
[0098] In some embodiments, as shown in FIG. 5, the micro lens
array 20 is fixed and the display panel 10 is controlled to move
along the preset path (shown by the arrow line) relative to the
micro lens array 20.
[0099] In some other embodiments, as shown in FIG. 7, the display
panel 10 is fixed and the micro lens array 20 is controlled to move
along the preset path (shown by the arrow line) relative to the
display panel 10.
[0100] In some other embodiments, as shown in FIG. 8, the display
panel 10 and the micro lens array 20 are respectively controlled to
move along respective preset paths (shown by the arrow lines in
different directions). The moving directions of the display panel
10 and the micro lens array 20 are opposite.
[0101] In order to achieve the parallel relative displacement
between the display panel 10 and the micro lens array 20, in some
embodiments, the display panel 10 and the micro lens array 20 adopt
different preset paths.
[0102] In some embodiments, as shown in FIG. 9, the at least one
preset path includes a first preset path D1 and a second preset
path D2. The first preset path D1 is different from the second
preset path D2.
[0103] In this case, as shown in FIG. 9, in the above described
S102, the display panel 10 is controlled to move along the first
preset path D1, and the micro lens array 20 is controlled to move
along the second preset path D2. In this case, in order to achieve
the parallel relative displacement between the display panel 10 and
the micro lens array 20, the plane where the first preset path D1
is located is parallel to the plane where the second preset path D2
is located.
[0104] For example, as shown in FIG. 9, both the plane where the
first preset path D1 is located and the plane where the second
preset path D2 is located are parallel to the light exit surface of
the display panel 10 or the light exit side surface of the micro
lens array 20.
[0105] Alternatively, both the plane where the first preset path D1
is located and the plane where the second preset path D2 is located
intersect with the light exit surface of the display panel 10 or
the light exit side surface of the micro lens array 20 in the same
angle.
[0106] It will be noted that the superposed pixels 102 are
generated around the intrinsic pixels 101 in the display panel 10,
or the pixel 101 is divided into a plurality of superposed pixels
102 when the manner shown in FIG. 5, FIG. 7, FIG. 8 or FIG. 9 is
adopted, and the manners and display principles thereof are the
same as described above, which will not be elaborated here.
[0107] Other embodiments for relative displacement between the
display panel 10 and the micro lenses 201 along the at least one
preset path will not be elaborated in the present disclosure.
[0108] Some embodiments of the present disclosure provide a
computer device, and as shown in FIG. 16, the computer device
includes a memory 200 and a processor 300. The memory 200 includes
executable instructions stored thereon, and the processor 300 is
configured to execute the executable instructions to implement the
display method of the display device as described above. The
computer device has the same technical effect as the display method
of the display device, and it is unnecessary to go into details
here. The above memory may include various media that can store
program codes, such as ROM, RAM, disk, and compact disc.
[0109] Some embodiments of the present disclosure provide a
non-transitory computer readable storage medium. The medium stores
executable instructions that, when executed by a display device,
cause the display device to implement the display method of the
display device as described above. The non-transitory computer
readable storage medium has the same technical effect as the
display method of the display device, and it is unnecessary to go
into details here.
[0110] Some embodiments of the present disclosure provide a display
device. The display device includes a display panel 10 and a micro
lens array 20 disposed on a display side of the display panel 10.
The micro lens array 20 includes a plurality of micro lenses 201
arranged in an array. Furthermore, the display device, as shown in
FIG. 1b, further includes a driving system 40, a controller 41, and
a signal processor 42.
[0111] In some embodiments, the display device further includes a
front frame, while the driving system 40 includes at least one
vibration platform.
[0112] In this case, in some embodiments, as shown in FIG. 13, the
display panel 10 is fixedly mounted in the front frame 50.
Furthermore, the micro lens array 20 is mounted on the vibration
platform 60, and the vibration platform 60 is configured to drive
the micro lens array 20 to move. For example, the vibration
platform 60 has a holding device for fixing the micro lens array
20, and the vibration platform 60 is provided with a guide rail
that matches the preset path, and the holding device is mounted in
the guide rail. In addition, the vibration platform 60 further
includes a driving unit connected to the holding device, for
example, an electro-motor or a hydraulic motor. Under the driving
action of the motor, the holding device may be driven to motivate
the micro lens array 20 to move along the guide rail, thereby
achieving the purpose that the driving system drives the micro lens
array 20 to move along the preset path.
[0113] In some other embodiments, as shown in FIG. 14, the micro
lens array 20 is fixedly mounted in the front frame 50. The display
panel 10 is mounted on the vibration platform 60, and the vibration
platform 60 is configured to drive the display panel 10 to move.
The setting manner of the vibration platform 60 is the same as the
setting manner above, and it is unnecessary to go into details
here.
[0114] Furthermore, in the case where both the display panel 10 and
the micro lens array 20 can move, as shown in FIG. 15, the driving
system 40 includes a first vibration platform 61 and a second
vibration platform 62. In this case, the display panel 10 is
mounted on the first vibration platform 61. The first vibration
platform 61 is configured to drive the display panel 10 to move.
The micro lens array 20 is mounted on the second vibration platform
62. The second vibration platform 62 is configured to drive the
micro lens array 20 to move.
[0115] The setting manners of the first vibration platform 61 and
the second vibration platform 62 are the same as the setting manner
of the above vibration platform 60, and they are unnecessary to go
into details here.
[0116] Furthermore, when the size of the display device is small,
the requirement for the displacement precision of relative
displacement between the display panel 10 and the micro lens array
20 is high. In this case, the driving system 40 is for example an
MEMS system. The MEMS system has a vibration platform with, for
example, a small size and a high movement precision.
[0117] The display device has the same technical effect as the
above described display method of the display device, and it is
unnecessary to go into details here.
[0118] The controller described in the above embodiments is
executed, for example, by a microprocessor programmed to perform
one or more of the operations and/or functions described herein.
Alternatively, the controller is implemented in whole or in part by
specially configured hardware (e.g., by one or more
application-specific integrated circuits (ASIC(s))).
[0119] The foregoing descriptions are merely some embodiments of
the present disclosure, but the protection scope of the present
disclosure is not limited thereto. For those skilled in the art,
various changes and modifications can be made therein without
departing from the spirit and essence of the disclosure, which are
also considered to be within the scope of the disclosure.
Therefore, the protection scope of the present disclosure shall be
determined by the protection scope of the claims.
